Mizuno Fli-Hi. The Mizuno Fli-Hi is an easy hitting alternative to long irons. The hollow design enables weight to be moved back from the face, creating a deep low centre of gravity for stability and high launch angle. A forged stainless steel face and neck ensures a soft pure feel and adjustable lie angle. Easier to get airborne than a long iron, solid at impact and more controllable than a fairway wood. Well suited to links golf the Fli-Hi is noted for its regular appearance at The Open Championship.
